Preheat oven to 325 degrees F . Grease and flour a 9x5 inch loaf pan. If you have some parchment paper, I recommend lining the bottom with a long strip for easy removal.
Sift together flour, salt, baking powder and baking soda. Set aside.
In a measuring cup, combine milk, vanilla and bourbon.
In a mixing bowl, using an electric mixer, beat butter and both sugars until creamy. Add eggs one at a time, beating 30 seconds after each eggs.
With a heavy duty scraper, add flour mixture and milk mixture alternately, beginning and ending with flour. When fully mixed, pour into pan.
Place on center rack and bake for 50 to 60 minutes (start checking at 50).
Cool cake in pan for about 10 minutes, the carefully invert onto a wire rack set over some foil or wax paper.
Make the glaze by mixing the sugar, bourbon and orange juice together in a little bowl. Brush glaze over warm cake and let cool completely.
Allow the cake to cool completely before serving. I think it tastes better on the second day.
